SPECIFICATION forming part of Letters Patent N0. 473,257, dated April 19, 1892. Application tiled January 21, 1891- Serial No. 378,507. (No model.)

To wll whom it may concern.-

Beit known that I, ANDRE\V GEORGE HILL, a citizen of the United States, and a resident of the city of Prescott, in the Province of Ontario and Dominion of Canada, have invented certain new and useful Improvements in Disk Cultivators, of which the following is a speci- 'fication, reference being had to the drawings forming part thereof.

This invention consists, first, in t-hecombination, withtwo disk gangs, of means for simultaneously increasing the angle of one .disk gang and diminishing the angle of the other gang, so that the harrow will be caused to move obliquely toward the side of the disk gang having the greatest angle, thereby permit'ting of the steering of the harrow by the driver, so that it may be caused to clear or dodgea hill that is out of line in the checkrows; second, in the combination, with two disk gangs, of meansfor independently adjusting the disk gangs to a given working angle and retaining the same at such angle;

. third, in certain other constructions and arz5 rangements of parts hereinafter described andclaimed.

In the drawings, Figure 1 is a rear elevation of a disk cultivator containing my improvements. Fig. 2 is a side view of the same. Fig. 3 is a plan view. Fig. 4 is aside View of the seat, with the clamp shown for retaining the rods tying together the handles operatingthe disk gangs.

a is the rear end of the pole, to which is 5 rigidly connected the main or cross beam Z).

c c are two down-hangers, in the lower end of eachof which are swiveled two disk gangs d.dnamely, in sockets at the points d! 1!!- 4othe main beam, are mado rigid to the pole by means of the braces e e e e. The disk gangs are capable of being reversed, so as to throw the soil out ardly as well as inwardly, which latter is their operation when arranged relatively to each other, as shown by the draw ings; but such disk gangs are not arranged so that their endswill have movement in the vertical plane, as thelatter quality is not necessary for adisk cultivator working in These down-hangers, together with check-rows, which work this harrow is prin- 59 cipallyintended to perform.

f'g are two handles respectively attached, to the top of the disk-gang beams h h by bolts aridnearly midway of said beams. The ends of these handles extend up to the drivers seat and within easy reach ofhis hands.

1' i are two bars. One end of each is 0011- nected, respectively, to the upper ends of the handles fg at j j by means of hooks taking into the eyes i" t' and connected together at 60 theirother ends by the sleeve 70 and set-screw 7a, the latter elements forming, when the proper adjustment is made, a clamp, and permitting ofa movement of both disk gangs by the shifting of the two handles thus bound together.

Z Z is a casting made of two plates, the upper member-Z being secured to thelower partof the drivers seat, and the lower member Z being" screwed up against the member 6 by the clamp-screw Z. The inner ends of the two bars 1' pass through openings in m in the .faces' of the plates Z 1'. Such clamp prevents all movement of the handles and consequently of the disk gangs when working at a given 5 angle. I

In'Figs. 1 and 2 the disk gangs are shown as being in line with each other, such position as they assume when going cit or onto the working field and before being set at a working angle. it. will be seen, Fig. 1, that the'handles recede from one another. If the disk gangs are reversedthat is to say, the one changed over to the down-hanger of the other, so that the disks will throw the dirt outwardlyinstead of inwardly-then the l1andles will incline or convergetoward each other. In the latter case, to give the disk gangs a working angle, they 1n ust be separated by means of the bars i '1; and clamps 7; I In c I the former case, as shown in Fig. 1, to give the disk gangs a working angle,'thc handles must, on the contrary, be caused to converge toward each other. r e

The disk-gang beams are supported .on the. 5 axles of the disk gangs by the standards 71 n, the'lower ends of which partially grasp the axles in a novel manner. (Described and claimed in another application for Letters Patent now pending.)

o are circular plates having rims p- 19', one of each secured to the center of the top of the disk-gang beam in front of the downhanger. 1

q-q' are two latches secured to bands r1" on the down-"ha 'igers, the hooked ends of which engage with the said rims p p, and thus retain the parts named and the handles connected therewith in an upright position.

The drivers seat is situated on the end of a standard or beam 3, which is secured in the bifurcated rear portion of the pole, as seen in Fig. 2.

The operation of the cultivator after the disk gangs have been adjusted to the proper workingangle(thewayto adj ustthesamefrom the position of the gangs shown in Fig. 1 or of reversing the gangs will be evident from the description of the mechanism above given) is as follows, namely: If the hill is out of line in the row being cultivated and lying to the left hand of thedr iver,the handlefis pushed] to the right hand and toward the center of the barrow, thus moving simultaneously theham die 9, the eiiectof which is to cause the disk gang (Z to assume a greater angle and thedisk gang (1 a lesscrangle than-the workinganglein other words, increasing the angle of the lefthand gang and diminishing the angle of the right-hand gang. This will cause the barrow to at once move sidewise and toward the side of the gang having the greatest angle namely, the lcft-han d sidethereby avoiding passing over the hill the harrowis approaching. The handles are as rapidly shifted again to have the disk gangs assume the normal workingangle after passing by the hill out of line. The positions of the disk gangs in Fig. 3 show the angles made by so shifting the handlesf and g. The letter a; shows where the axial lines of the disk gang axlesif prolonged would intersect under such circumstances, and the letter y tho point where such lines would interscct when the said gangs areagain brought into the position of a normal working angle. In the latter case the harrow moves in thcdi rection of the arrow ,2, Fig. 3. By moving the handles in the other direc1ion-that is, to the left hand-the harro w would be caused to move toward the right hand of the driver, and thus avoid crossing a hill out of line on that side. Thus the harrow by such sim ultaueous movements of the handles to the right or to the left can be steered by the driver to avoid cutting through the hills which may be out of line in the check-rows. a

It is desirable at the end of the rows to lift the harrow over the hills, so as to leave them intact while starting to work back in the other direction, and to do this with as little trouble and loss of time as possible. I accomplish this end in the following manner, namely: At the rear of each of the handles gfand at a short distance above their attachment; to the disk-gang beams I pivot a leg or standard t 15. At the lowerend of each of these legs is a carrying-wheel u a, with sufficient breadth of periphery to keep it from sinking into the soil when counterpoising the disk gang thereon. These legs 15 t are inturn braced on each side to the disk-gang beams by the braces '12 u c" 0, two'of them shorter than the others, so as to give the proper lateral position to the handles 9 f. These handles are held in the proper upright position by the latches q q. These latches being raised from ofi of the rims p 1) will cause the carrying-wheels a u to drop to the ground, as shown by dotted lines in Fig. 2. Now by hearing down on the handles g f, so lowered, (see dotted lines, Fig. 2,) the carrying-wheels u u form fulcra and the disk gangs will be lifted clear of the ground, and thus at the ends ofthe rows permit of the'manipulation of the cultivator, as

above stated. When the handles are again raised, the latches q q will again engage with the rims p p and the barrow be again in a.

condition to do duty back. along the check IO\VS.

I clai m -1. In disk cultivators, the combinatiomwith two disk gangs, of two handles attached thereto and adj ust-able bars connected with said handles for simultaneously increasing the angle of one disk gang and diminishing the angle of the other gang, substantially as described. 2. In disk cultivators,.tl1e combination,with two disk gangs, of handles secured to the diskgang beams at their lower ends and .contain ing standards and carrying-wheels, and circular plates containing rims placed on the disk-gang beams and the latches engaging with such rims, substantially as described.
